  • Methods for positively assuring the equal distribution of liquid and vapor at piping junctions in two phase flow by intermittent flow interruption
    Patent number: 6056001
    Abstract: Equal distribution of two phase fluid between tow outlets is assured by an assembly which switches full fluid flow alternately between the two outlets on a timed basis. Distribution can be made for either impact T or branch T junctions without a quality variance as full flow is always directed into one or the other of the two outlets.

  • Hydrotreating process with two phase flow splitting and heat recovery
    Patent number: 5738779
    Abstract: In a hydrotreating process a two phase flow splitter is used in combination with parallel heat exchanger trains for heat transfer stability. Flow maldistribution of liquid and vapor between heat exchanger trains is thereby avoided without more complex feedback control. The two phase flow splitter is inherently phase volume ratio stable. Prior methods of flow splitting were only phase volume ratio metastable. Improved heat recovery at lower equipment cost is thereby achieved.
